>>> import re >>> words = [“hello”, “18hs”, “18aaa”, “21hr”] >>> [w for w in words if not re.match(r’\d+h’, w)] [‘hello’, ’18aaa’] This loops over the list and keeps the items that don’t match the regex \d+h, which means “one or more digits followed by an h”. If you need to keep strings like 7hg, … Read more
You can do that as: print len(set(str(s))) The str() casts the int as a string The set() takes the unique elements of the string and creates a set of it The len() returns the length of the set Examples >>> print len(set(str(s))) 5 s = 1324082304 >>> print len(set(str(s))) 6 10 solved Count of different … Read more

It’s because you are importing one before printing “top level two.py”. if one.py looks like this: print(“top level one.py”) def func(): #do something if __name__ == ‘__main__’: print(“one.py being run directly”) else: print(“one.py has been imported”) and with the two.py code above, then one.py is run first, when it is imported. Because one is running … Read more
Use enumerate for count,item in enumerate(input_list,1): # your code print(count) 2 Or you can increment a counter while iterating : count = 0 for i in input_list: count += 1 # your code print(count) 2 solved Counting the number of lists that are printed [closed]
The for loops are nested, from left to right. You can write it out as regular loops like this: words = [] for line in open(‘words.txt’, ‘r’): for word in line.split(): words.append(word) So the expression before the for loops is the final value added to the produced list, and all the for loops (and any … Read more

As mentioned in the comment above your program do its job and perfectly described the Fibonacci sequence. Here I implement the recursive version and then compare the result with your implementation (explicit form). import math def staircase(n): term_a = ((1 + math.sqrt(5)) / 2) ** n term_b = ((1 – math.sqrt(5)) / 2) ** n … Read more
You may use regular-expression for the same. Here is an approach to do the same import re pattern = ‘[a-zA-Z]+’ country = [‘India12′,’Bolivia (SA)’, ‘Australia17 (A)’] country_names = map(lambda x:re.search(pattern,x).group(),country) 0 solved Remove parenthesis and numbers from names?
Your question seems to have two main parts to it: how do I get inputs in Python and how do I save data to a file in Python. To get input from the terminal: >>> data = input(‘Input: ‘) >>> Input: hello, world! To save to a file: >>> with open(‘output.txt’, ‘w’) as f: >>> … Read more
you should aggregate by column and then sum the results, try this: Notice that, the patient name should should have a numerical counter for keeping track. import pandas as pd import datetime import numpy as np # this a dummy set, you should have already this in your data frame dict_df = {‘Patient’: [1,2,3,4,5], ‘Positive’: … Read more
The answer for the first problem: You never defined first_name outside of Players_input. This value is just stored inside the function, and get’s deleted afterwards. (more about this in the link added by gjttt1) There are two ways to solve this: You could make first_name global. But this is a bad style, so I wouldn’t … Read more
